Until a recent update, SharePoint team sites always had a left side vertical navigation menu. Communication sites always had a top horizontal navigation menu that could be a cascading or mega menu style. Recently, Microsoft rolled out the ability to change a team site’s navigation from vertical (side) to horizontal (top).

Note: This change only applies to team site types. Communication sites are still top horizontal only.
Below are the steps to swap your team site’s navigation orientation. You must be a site owner to perform these steps.
How to change SharePoint team site navigation from left side to top
- Navigate to the team site for which you’d like to switch the navigation orientation.
- Click the settings wheel in the upper-right corner.
- Select Change the look.
- Select Navigation.
- Choose Horizontal and then choose either Mega menu or Cascading for menu style.
I think I created it as a communication site, not a team site. So that’ll likely explain it. I see no easy way to change it, apart from deleting and recreating.
Thanks for your feedback. Appreciated.
That’s correct – there’s currently no way to switch a communication site to a team site. You could, however, create a new team site then at least move your files easily by using a “select all” and “move to” action in the document library. If you have access to a migration tool like ShareGate, that could help copy much more over as well. Good luck!
I don’t get the horizontal/vertical option 🙁
Any thoughts?
Do you know if your site a team site or a communication site? Team sites will show you a number of members in the upper right corner of the site by the following option. If you don’t see a number of members, it’s a communication site and won’t have the ability to switch navigation orientation. Does that help?
